2017-01-24PR ld/20828: Reorder the symbol sweep stage of section GCMaciej W. Rozycki4-54/+71
Complement commit 81ff47b3a546 ("PR ld/20828: Fix linker script symbols wrongly forced local with section GC") and move the symbol sweep stage of section GC from `elf_gc_sweep' to `bfd_elf_size_dynamic_sections', avoiding the need to clear the `forced_local' marker, problematic for targets that have special processing in their `elf_backend_hide_symbol' handler. Set `mark' instead in `bfd_elf_record_link_assignment' and, matching changes from commit 3bd43ebcb602 ("ld --gc-sections fail with __tls_get_addr_opt"), also in PowerPC `__tls_get_addr_opt' handling code, removing a: FAIL: PR ld/20828 dynamic symbols with section GC (version script) test suite failure with the `score-elf' target. The rationale is it is enough if symbols are swept at the beginning of `bfd_elf_size_dynamic_sections' as it is only in this function that the size of the GOT, the dynamic symbol table and other dynamic sections is determined, which will depend on the number of symbols making it to the dynamic symbol table. It is also appropriate to do the sweep at this point as it is already after any changes have been made to symbols with `bfd_elf_record_link_assignment', and not possible any earlier as calls to that function are only made just beforehand -- barring audit entry processing -- via `gld${EMULATION_NAME}_find_statement_assignment' invoked from `gld${EMULATION_NAME}_before_allocation' which is the ELF handler for `ldemul_before_allocation'. bfd/ PR ld/20828 * elflink.c (bfd_elf_record_link_assignment): Revert last change and don't ever clear `forced_local'.

2017-01-24PowerPC dynamic relocationsAlan Modra3-306/+371
This patch fixes a number of issues with powerpc dynamic relocations. 1) Both ppc and ppc64 were emitting more dynamic symbols and relocations than necessary, due to not supporting static linker resolution of tls_index entries for __tls_get_addr_opt. This meant that any @got@tlsgd or @got@tlsld reloc needed to make their symbols dynamic and generate dptmod and dtprel relocs for the dynamic linker. That would have been passable, but what happened was that practically all @got relocations resulted in their symbols being made dynamic and dynamic relocations emitted against the GOT entries. (Mostly visible on ppc32 executables since ppc64 gcc really only uses @got style relocs for TLS.) 2) The PowerOpen syntax was not supported with __tls_get_addr_opt. DTPMOD/DTPREL relocs on tls_index TOC entries did not use the trick of forcing dynamic symbols and relocations so those entries always resulted in the full __tls_get_addr processing. gcc doesn't use the PowerOpen syntax for TLS, and normally such code would be optimized to TLS IE or LE so the impact of missing this support was minimal. 3) In an executable, relocations against GNU indirect functions always used the value of their PLT stub. While this is correct, it is better in some cases to use a dynamic relocation. An extra dynamic relocation can mean that calls via function pointers need not bounce through the PLT stub at runtime. The patch also tidies the PLT handling code in ppc32 allocate_dynrelocs. Allocating PLT entries after other dynamic relocs allows the PLT loop to omit special handling for undefined weak symbols, and that in turn allows the loop to be simplified. bfd/ * elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Merge two cases where dynamic relocs are preferable. Allow ifunc too. (ensure_undefweak_dynamic): New function. (allocate_dynrelocs): Use it here. Move plt handling last and don't make symbols dynamic, simplifying loop.

2017-01-18PR ld/20828: Fix linker script symbols wrongly forced local with section GCMaciej W. Rozycki2-3/+15
Fix a generic ELF linker regression introduced with a chain of changes made to unused input section garbage collection: - commit 1a766c6843ce ("Also hide symbols without PLT nor GOT references."), <https://sourceware.org/ml/binutils/2011-09/msg00076.html>, - commit 1d5316ab67e1 ("PR ld/13177: garbage collector retains zombie references to external libraries"), <https://sourceware.org/ml/binutils/2011-10/msg00161.html>, - commit 6673f753c019 ("Fix PR 12772, garbage collection of dynamic syms"), <https://sourceware.org/ml/binutils/2011-12/msg00077.html>, causing the garbage collection of unused symbols present in a DSO involved in a link to make identically named symbols ordinarily defined (i.e. not hidden or PROVIDEd) by a linker script local, even though the latter symbols are supposed to be global as if no DSO defined them as well. This is because linker script assignments are processed very late as `lang_process' proceeds, down in the call to `ldemul_before_allocation', which is made after the call to `lang_gc_sections' to do input section garbage collecting. Consequently if unused, then any such DSO-defined symbol has already been garbage-collected and internally marked local. It would ordinarily be removed from dynamic symbol table output, however a linker script assignment correctly replaces its original definition with the new one and enters it into the dynamic symbol table produced as it is supposed to be exported. The original local marking is however retained making the symbol local in the dynamic symbol table and therefore not available externally. This also causes a sorting problem with the MIPS target, which does not expect non-section local dynamic symbols to be output and produces an invalid binary. Fix the problem then, by removing the `forced_local' marking for the offending case and add suitable test cases. First to verify that unused symbols ordinarily defined with linker script assignments remain exported in the context of input section garbage collection whether or not a DSO defining identically named symbols is present in the link. Second that a linker version script still correctly retains or removes such symbols as requested. bfd/ PR ld/20828 * elflink.c (bfd_elf_record_link_assignment): Clear any `forced_local' marking for DSO symbols that are not being provided. ld/ PR ld/20828 * testsuite/ld-elf/pr20828-1.sd: New test. * testsuite/ld-elf/pr20828-2a.sd: New test. * testsuite/ld-elf/pr20828-2b.sd: New test. * testsuite/ld-elf/pr20828.ld: New test linker script. * testsuite/ld-elf/pr20828.ver: New test version script. * testsuite/ld-elf/pr20828.s: New test source. * testsuite/ld-elf/shared.exp: Run the new test.
